  1. Send a notification to the customer together with an official document - an expert opinion from an insurance agent, a licensed car repair shop, a statement of violation, etc. for the amount due and payable by the customer.
  2. Wait for up to 10 days for a reply to the email sent to its customer.

  • The cash refunds to customers shall be performed only by a Reversal/Refund transaction onto the card with which the initial transaction was made.

How to proceed in case of an unsuccessful transaction?


  • In case the POS terminal device does not print out a receipt or if there is “Transaction rejected” written on it, this means that the payment was unsuccessful.

  • In order to check which is the latest successful transaction, you have to press the button for a receipt copy on the real POS terminal device.
